ECO-WORTHY Solar Battery Maintainer is the perfect solution for charging the batteries of boats, SUVs, RVs, electric fences, accessory batteries, and much more. Over time batteries naturally lose power and even can go flat. ECO-WORTHY Solar Battery Maintainer will help you maintain a healthy battery by converting solar energy into a usable 12V DC current to keep your battery topped off at a stable level.

Key Features
More Efficient
30% high conversion rate crystalline silicon material + 95% high transmittance ETFE material, greatly improving the charging efficiency of solar chargers, which can achieve the most ideal charging effect in a limited space.
Built-in Blocking Diode
The charging algorithm is upgraded, and the charging efficiency is increased by 20%-30%. Provides multiple protections such as overcharge protection, over discharge protection, reverse polarity protection, etc.
Easier to Monitor
The solar panel junction box has indicators, which help visually monitor the working status.
More Robust and Durable
This solar battery maintainer is covered with ultra clear PV glass which is more efficient, and also with Durable ABS plastic housing which makes this solar panels charger more stronger.
Lightweight and Portable
The thickness is only 1/3 of the rigid panel; the weight is light and it is easy to carry. Comes with a SAE cable kit, plug and play, widely used in 12V batteries and DC charging equipment, such as cars, RVs, boats, etc.

Why do we need a solar battery maintainer
Three reasons to own a Solar Battery Trickle Charger
1. Batteries Naturally Discharge - Automotive batteries naturally discharge when not in use.
2. Vehicles have a small but constant battery drain - Modern vehicles have upwards of 30 body control modules (computers), alarm systems, immobilizers and lock monitoring. These units all consume electricity from the battery. That's why in a week or two with no or little vehicle use the battery can become discharged.
3. Battery life is shortened if it is not kept charged - A 12V battery that is not correctly maintained above 12.4V can suffer from sulphation. Sulphation is the main cause of battery failure. That's why the auto battery easy goes to dead when vehicles are left standing for long periods.

Modern cars, feh

I have a Subaru, a VW, and a Prius Prime. None of them have a single cigarette lighter outlet that can be easily made to stay on while the car is shut off. Ironically all the manuals state that this is in order to save the battery.
